[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column-beam joint for a housing unit constructed by connecting a plurality of columns and beams.

0002

BACKGROUND ART In recent years, a construction method has been adopted in which multiple types of housing units manufactured in advance at a factory are transported to a construction site and then assembled there to construct a housing. Normally, the housing unit 10 has a short side beam (beam on the gable side of the housing unit 10) 13 and a long side beam between the upper ends and lower ends of four columns 12 arranged at the four corners, as shown in FIG. A box-shaped frame 11 is formed by interconnecting four upper beams 15 and four lower beams 16 each consisting of side beams (beams on the girder side of the housing unit 10) 14, and includes internal and external wall panels, ceiling panels,
It is constructed by attaching floor panels, etc. By combining these housing units 10, an industrialized housing 20 shown in FIG. 11 is constructed.

By the way, the connection between the columns 12 and the beams 13 and 14 that constitute the frame 11 of this type of housing unit 10 is as follows.
For example, a joining method using an inner diaphragm method or a joining method using a through diaphragm method is common.

That is, in the inner diaphragm method of joining, a joining fitting is provided on the pillar without dividing the column, and the long side beam 14 and the short side beam 13 are connected to this joining fitting. At this time, an inner diaphragm for reinforcement is provided inside the pillar 12 on the extension of the joining metal fitting.

However, welding of the inner diaphragm into the column 12 must be carried out inside the narrow column 12 and at a position that is somewhat inward from the end.
This is extremely difficult and difficult work. Furthermore, it is difficult to mount the inner diaphragm at a precise mounting position, that is, on an extension of the joining fittings. If the inner diaphragm is not installed in the correct position and is installed out of alignment with the fittings, the force flow transmitted from the beam will be transmitted directly to the column and not to the inner diaphragm, causing the column to become structurally unstable. As the inner diaphragm becomes weaker, there is no point in installing the inner diaphragm.

Therefore, as a method to eliminate these problems, as shown in FIG. 9, the column 12 is divided and a joining fitting 25 serving as a diaphragm is attached through the divided portion, and the column 12 and the beam 13 are attached to this joining fitting 25. , 14 has been proposed.

[0007]

[Problems to be Solved by the Invention] By the way, in the through-diaphragm type joining method, there is no need to weld the inner diaphragm inside the column 12, and the flow of force from the beams 13 and 14 is directly transmitted to the diaphragm. , it becomes a strong pillar structurally. However, in this method, the positions of the pillars 12 and the through-diaphragm type joining fittings 25 tend to shift when they are connected, which causes inconvenience.

[0008] That is, when combining a plurality of housing units 10, especially when combining units on upper and lower floors,
The units are positioned with respect to each other by engaging a column head guide pin or the like provided on one side of the metal fitting with an engagement hole formed on the side of the other metal fitting. However, the pillar 12 is used as a reference plane during actual outfitting such as attachment of internal equipment. Therefore, there is a problem in that the interior finish and the position of the floor plan are different from the designed position where the guide pin position is the module core and the module core is used as a reference.

SUMMARY OF THE INVENTION An object of the present invention is to provide a column-beam joint for a housing unit that has sufficient rigidity without welding within the column and can be attached to the column without shifting.

0010

[Means for Solving the Problems] The present invention provides a column-beam joint for a housing unit that includes a plurality of columns and a plurality of beams connected at right angles to each other between the ends of these columns. A horizontal first end member having a joint with two beams that are at right angles to each other; and two beams that are provided horizontally corresponding to the first end member and that are at right angles to each other. and a second end member having a joint portion, the first end member is inserted and fixed into a horizontal groove formed halfway in the column of the housing unit, and the second end member has a joint portion of the housing unit. It is used as a column-beam joint fitting for housing units to which one end of the column of the unit is fixed.

[0011]

According to the present invention, the first end member is inserted into the horizontal groove formed near one end of the column, and the second end member is fixed to the end surface of the column. Since the horizontal groove of the column was formed halfway through the column, the column was not cut, and therefore, there was no misalignment between the column and the joining fitting. Further, since the first end member is inserted halfway into the column, it serves as both an inner diaphragm and a through diaphragm, making it easy to weld and having high strength, thereby achieving the above object.

Regarding the joining of the joining fitting 1 and the long side beam 14, as shown in FIG. 8, the joining parts 2B and 3B of the first end member 2 and the second end member 3 have the same shape, Moreover, the joint parts 2B and 3B have the same shape as the joint part 2A with the short side beam 13. That is, the joint portion 2B,
The bent horizontal portions 2D and 3C of the beam 14 are shaped so as to come into contact with the inside of the upper flange 14A and the outside of the lower flange 14B of the beam 14.

As shown in FIG. 2, the side member 4 is formed of a plate material having an L-shaped cross section, and the first end member 2 and the second end member 3 are fixed in parallel above and below. At this time, the first and second end members 2 and 3 are connected to the beams 13 and 1.
It is fixed at a height of 4.

At both ends of the side member 4, the beams 13,
Joint portions 4A and 4B are formed to join the end portions of 14. As shown in FIG. 2, the joints 4A, 4B are formed so as to come into contact with the inner sides of the webs 13C, 14C at the ends of the beams 13, 14. That is, the tip of the side member 4 is bent inward at a substantially right angle, ensuring the thickness of the webs 13C, 14C of the beams 13, 14, and then further folded outward at a substantially right angle.

A circular opening 4 is provided on the side surface of the side member 4.
C is formed. This opening 4C is formed when the pillar 12 of the housing unit 10 and the joining fitting 1 are joined.
It is formed so as to be located on the side surface of the pillar 12.

[0022] Here, the pillars 12 of the housing unit 10 will be explained. Near the end of this pillar 12, a horizontal groove 12A parallel to the end surface of the pillar 12 is formed. horizontal groove 1
2A is formed halfway up the pillar 12 as shown in FIG.
When the end surface of the second end surface member 2 is attached to the inner surface of the second end surface member 3, the first end surface member 2 is inserted.

Next, the operation of this embodiment will be explained. The first and second end members 2 and 3 are fixed to the upper and lower sides of the side member 4. At this time, the first and second end members 2 and 3 are fixed so that their joint parts 2A and 3A, 2B and 3B, etc., face each other and are parallel to each other.

In order to join the joining fitting 1 constructed in this manner and the pillar 12, a first groove is inserted into the horizontal groove 12A of the pillar 12.
Insert the end member 2 until it stops. At this time, the end face of the pillar 12 is in contact with the surface of the second end face member 3.

When the first end member 2 is completely inserted into the horizontal groove 12A of the column 12, the end surface of the column 12 is welded to the second end member 3, and then the first end member 2 and the column 12 are welded together. to fix. Further, the side surface of the pillar 12 and the periphery of the opening 4C of the side member 4 are also welded.

After joining the joining fitting 1 to one end of the column 12, the joining fitting 1 is subsequently joined to the other end, and the beams 13 and 14 are joined to each end. When joining the beams 13 and 14, the upper short side beam 13 and the lower short side beam 13 are first connected between the upper and lower ends of the gable side frame, that is, the pillar 12, according to the procedure. Next, the gable side frames are connected to each other by upper and lower long side beams 14 to form the frame 11 of the housing unit 10.

According to this embodiment as described above, the following effects are achieved. That is, the pillar 12 and the joining fitting 1 are joined by inserting the first end member 2 into the horizontal groove 12A formed halfway in the pillar 12, and since the pillar 12 is not divided, the joining with the pillar 12 is performed. The position with the metal fitting 1 will not shift, and therefore, problems such as the finish of the interior of the building differing from the designed position will not occur due to this.

Also, the first end member 2 is inserted into the horizontal groove 1 of the column 12.
Since the first end member 2 is inserted into the inner diaphragm 2A, a part of the first end member 2 becomes an inner diaphragm and a part becomes a through diaphragm. Since the position of the first end face member 2 can be secured by accurately extending the horizontal groove 12A, the problem of difficulty in positioning it as with the conventional inner diaphragm is solved. At the same time, the outer periphery of the pillar 12 and the first end member 2
The welding inside the pillar 12 is no longer necessary.

Furthermore, since the first end member 2 is an inner diaphragm and its mounting position is accurately exposed, the beam 13,
The column-beam joint fitting 1 allows smooth transmission of force from the column 14 and has sufficient structural rigidity.

The column 12 and the joining fitting 1 are welded together by the first and second end members 2 and 3, and the side member 4 is also welded to the opening 4C.
Since it is welded and fixed through the , a more reliable connection is achieved.

A second embodiment of the invention is shown in FIGS. 4-6. As shown in these figures, this embodiment eliminates the need for the side member 4 in the first embodiment, and
Moreover, the shapes of the beams 13 and 14 are slightly changed. Therefore, the same reference numerals are given to structurally the same parts, and explanations are also omitted or simplified.

The column-beam joint fitting 20 of this embodiment is composed of a first end member 2 and a second end member 3. These first and second end members 2 and 3 are the first and second end members 2 and 3 of the first embodiment.
It is the same as the end members 2 and 3, and therefore the beams 13 and 14
It has joint parts 2A, 2B, 3A, and 3B, respectively. Further, the first end member 2 can be inserted into the horizontal groove 12A of the column 12.

In this embodiment, the web 13C of the beams 13 and 14
, 14C have a protruding shape. As shown in FIGS. 4 to 6, the first and second end members 2 and 3 are fixed to the column 12, and the beams 13 and 3 are attached to the first and second end members 2 and 3, respectively.
When the beams 14 are joined, the web 1 of the beams 13 and 14
Parts of the back parts 13C, 14C are formed into protrusions 13D, 14D so that the parts 3C, 14C cover part of the side surface of the pillar 12.

[0034] In addition to the same functions and effects as in the first embodiment, this embodiment also has the added effect of reducing the number of parts because the side member 4 is not required. In addition, the beams 13 and 14 have protruding portions 13.
Since D and 14D are formed, the column-beam joint can have sufficient strength even without the side member 4.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but includes the following modifications.

That is, in the first embodiment, the first and second
Although the end members 2, 3 and the side member 4 are constructed by assembling separate members, the present invention is not limited to this, and they may be integrally formed by, for example, press molding.

Further, the opening 4C of the side member 4 of the first embodiment does not have to be circular, and may be, for example, a square opening. In short, when the pillar 12 is joined to the joining fitting 1, it is sufficient that the side member 4 and the pillar 12 can be joined through the opening 4C.

[0038] In addition, the specific structure and shape for carrying out the present invention may be other structures as long as the object of the present invention can be achieved.

[0039]

[Effects of the Invention] As described above, according to the present invention, it is possible to provide a column-beam joint fitting for a housing unit that has sufficient rigidity without welding within the column and can be attached to the column without shifting. .
